Notes: Insane field with two former No. 1s and an additional Slam champ all unseeded…The Top 3 seeds are current or former No. 1s…Tough opening-round matches are (5) Na vs. Tamira Paszek then the winner of Venus and (WC) Medina Garrigues, (3) Azarenka vs. Pavlyuchenkova, (11) Petrova vs. a qualifier then likely Kuznetsova, (16) Ivanovic vs. a qualifier then likely her Serb countrywoman Jankovic, (9) Stosur vs. the clay-savvy Suarez Navarro, and (2) Sharapova vs. a qualifier then likely Peng…No blue clay this year…Former champs in the field are Serena Williams (2012) and Kvitova (2011).
